My civic 2000 D16 non-vtec is having a black smoke and bad fuel average around 5 kilometres per liter. All general tuning is done. What could be the possible reason?
anything from wrong ecu, bypassed CEL, no oxygen sensor, leaking injector, bad fuel pump pressure regulator, bad sparkplugs, bad coil, bad plug wires, bad distributor etc etc
this is classic case of extremely rich running engine.
I have got everything checked expect Distributor. Will get it checked anytime sooner.
Open the cap and share the picture of cap here.
What cap?
Distributor cap.
